The temperature of an object actually measures the degree of agitation of the molecules that compose it. The more an object is hot, the more its molecules are agitated by rapid and erratic movements; this is called thermal agitation. It is said that an object is at a temperature of absolute zero when its particle …
Our natural satellite, the Moon, has been attracting people’s views for more than one millennium. It is the second brightest object in the sky after the Sun and in many ways has an impact on earthly life, for example, it is thanks to the Moon that there are ebb and flow. The distance to the …
In giant detectors that are capable of reconstructing what happened during collisions, and all this in a very high collision rate environment, the events (an event is a collision with all of its resulting particles) are studied. They can be compared to extremely large three-dimensional digital cameras that can take 40 million “sequences” per second …
The great challenges of today’s science require infrastructures and monstrous investments, among which are the Large Hadron Collider (LHC) – the particle accelerator that started on 10 Sept 2008, the most powerful in the world -, the Pierre Auger Observatory – the largest cosmic ray detector of the moment-, the Cassini Huygens probe – the …
Find out how and why string theory modifies the spacetime equations of Einstein. If string theory is a theory of gravity, then what is the relationship between strings, gravitons and spacetime geometry? Strings and gravitons The simplest case to imagine is a single string traveling in a flat spacetime in d dimensions. As the string …
There are certain aspects of science that simply cannot be denied, no matter how much some people might try to deny them. For example, there are some people today that deny the fact that the earth is round. Today, we’re going to take a look at the simplified version of the theory of relativity, a …
The Einstein equation predicts several possible ways for the Universe to evolve in time and space. What are these predictions, and how do they equate themselves to observation?

A Bible-based assumption of a few thousand years old was made by Isaac Newton. Einstein believed in a World that was steady-state, ageless. Since then, somewhere in the centre, data obtained from the Universe places the probable response. First Ingredient: Quantum mechanics In the early 20th century, it was realized that the stability of atomic …
How Old is the Universe? (All Calculations so far) Read More »
Everything in this universe is manifested to our eyes and instruments in two well-known forms: matter and energy. This simple fact, which is true to how far we have come to observe – and at this point, we have come to observe very far – has given rise to numerous scientific, philosophical and even theological …
This baryonic matter that is so well known to us, at its most basic scale, is composed of quarks and usually accompanied by leptons. Leptons (such as electrons or neutrino) are subatomic particles that are subject to electromagnetism, gravity, and weak interaction, but not strong interaction (which is the strongest force in the universe, laying …
